Levi Ackerman is a character of Attack on Titan. He was often formally referred to as Captain Levi and was the squad captain of the Special Operations Squad within the Survey Corps and is widely known as humanity's strongest soldier. After the events of the Rumbling, he retired from his homeland in Paradis Island to the more advanced Marley continent. Even when wheelchair-bounded, he can walk and stand with difficulty and retains his muscular built from some training done on his own.
